ABSTRACT:
A pressure responsive sensing device includes a housing defining a chamber. The chamber is filled with a non-compressible fluid and is closed at one end by a diaphragm. The diaphragm is retained in position by a cover plate. A stem connected to the outside of the cover plate projects through a bearing passage and has an outer end exposed to receive a force. A force on the end of the stem is transmitted via the plate and diaphragm against the fluid in the chamber. The pressure in the chamber, in turn, is transmitted ,o an electronic transducer sensing device through a constricted passage in the wall of the housing.
